Motion Forces Work and Energy Electricity Waves
100
What is the standard (SI) unit for speed and acceleration?
meter per second , meter per second squared
100
What is inertia and how is it related to a passenger on a roller coaster?
Roller coasters use gravity and inertia. Inertia and the gravittt will give the force of acceleration making the coaster go up, down, and around the track
100
what is work ?
applying a force over a distance
100
What is the difference between and opens and closed circuit?
a open circuit has breaks in the wires and a closed is a full circuit with no breaks
100
What is needed for all waves to continue moving
energy
200
What is the difference between distance and displacement ?
Displacement is how far an object moves from its original posistion and distance is how far the object is
200
What is the difference between weight and mass?
weight is the object due to gravity and mass is the resistance to acceleration when force is applied
200
what are the units of energy
joules
200
How do opposite and like charges react to each other?
like charges repel and opposite charges attract
200
What is the relationship between the frequency and wavelength of a wave?
the relationship is that both frequency goes up and wavelength goes up
300
What does the slope of a position vs. time graph tell us? and What does the slope of a velocity vs. time graph tell us?
speed and acceleration
300
What is net force ?
the sum of all forces of an object
300
What is the law of conservation of energy?
energy cannot be created nor destroyed
400
What is the difference between a direct current (DC) and a alternating current (AC) ?
direct currents lets the electric charge only flow in one direction, and a alternating current let’s the electric flow in many directions
300
What is the difference between ultrasonic and infrasonic ?
ultrasonic is above what we are able to hear and infrasonic is below what we are able to hear
400
What is the difference between speed and velocity?
speed is how fast something is moving and velocity is the speed of something in a given direction.
400
What is the law of universal gravitation ?
an object that has a force directly proportional to the product of their masses and inversely proportional to the other object
400
What is energy
ability to do work that can cause a change in movement
400
What are the three primary colors of light?
red green and blue
500
What is meant by positive, negative, and 0 acceleration
positive means the acceleration is speeding up (increasing) , negative means the acceleration is slowing down (decreasing), and 0 acceleration means it’s at a stop
500
What two factors in the universal law of gravitation are most important in determining the force of gravity between two objects ?
mass and distance
500
What is potential & kinetic energy?
potential energy is an object that can store energy as the result of its posistion & kinetic energy is energy of motion
500
What are the three primary colors of pigments
Yellow , Cyan, and Magenta
